EMBROIDEVRING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 262,742, dated August15, 1882.

Application filed June 10, 1882. (No model.)

To all whom it may concern:

Beitknown that I, EMIL GORNELY, of Washington city, in the District ofColumbia, a resident of Paris,in the Republic of France, have invented anew and useful Improvement in Embroidering-Machines,whichisfully setforth in the following specification.

In Letters PatentNo. 228,445, of June 8, 1880, I have described certainimprovements by means ofwhich asecond thread is wound around the needleor the needle-thread of the Bonnaz embroidering machine, whereby acordingstitch is produced. As described in the speciiication of saidpatent, the rotary thread-carrier b of said machine received itscontinuous rotary motion from the main shaft D of the machine by meansof the gearings and pinions Q, N, It, T, K, L, and B. The rotation ofsaid thread-carrier was therefore an invariable one, as it depended fromthe regular revolutions of shaft D. The consequence was that when thedirection of thefeed ofthe machine was changed by turning the crankhandle S the cordingseam produced by the machine became variable inthickness, as the thread, according to the direction of the feed, waswound around it, either d uring an entire revolution or during a part ofit, or even during more than an entire revolution.

The present invention consists mainly in certain improvements,hereinafter described, whereby the thread carrier, while rotating aroundthe needle,can be governedby thecrankhandle, which also controls theuniversal feed, so that the thread-carrier follows the direction of thefeed. This being the object of the present invention, I will describethe mechanism which is employed to obtain it.

Figure 1 represents an elevation ofthe entire machine. Fig. 2 representsa section through the arm which contains the present improvements. Figs.3 and 4 represent detached views, hereinafter to be described.

D represents the main shaft of the machine.

C and E represent two levers, which are pivoted at c e to the frame ofthe machine. They are actuated by a double-grooved cam, F, (secured toshaft D,) into which extend the two friction-rollers fand 7c. Theextremities of the levers are provided with friction-rollers l andm,which reach into the collars n o of two concentrical cylinders orsleeves, I M. 'The inner sleeve, M, is adjusted upon a shaft, O, and canslide thereon freely. The exterior sleeve, I, is adjusted upon the innersleeve, M, and can slide freely on the latter.

N represents a frame, shown in section at Fig. 2 and in a side view atFig. 3. Its cylindrical part is fitted at P into the frame of themachine, and can turn therein freely, and the end of shaft O is securedto its outer part by means ofa pin, S. The shaft Q can turn freelywithin the frame N, and the bevel-wheel v is secured to and turns withsaid shaft. Another shaft, w, is tted transversely within the frame N,and has the bevel-Wheel 3 secured to it. To the latter is also secured acrank, 4, whose crank-pin 5 is connected to the stud 6 of the outersleeve, I, by means of a pitman, 7. An-

other crank, 8, is secured to the other end of shaft w and at rightangles to crank 4, and is connected with the stud 9 of the inner sleeve,M, by means of pitman 10. The stud 9, which is secured to the innersleeve, M, passesin its movement through the open mortise 11 of sleeveI.

When shaft D turns it operates levers C E, which impart a rectilinearreciprocating motion to the cylinders M Lwhich motionis transmitted bypitmen 7 and l0 to the cranks 4 and 8, imparting to them, to their shaftw, and consequently to the pinions 3, o, It T, K, L, and B andthread-carrier b, a rotary motion.

The shaft O can be turned by the crank-handle S through the pinions r,u, y, and U V. A square nut, q, Figs. 3 and 4, is secured to said shaftO and fits within sleeve M, so that when the shaft O is turned by thecrank S the two sleeves M and I and the studs and pitmen connected withthem, as well the frame N, to which said shaft is connected by pin S,are turned about the axis of shaft O as a center, and pinion 3 being ingear with pinion o, it turns the latter, and consequently the pinions RT, K, L, B and thread-carrier b. Thus the threadcarrier b and its spoolG, both secured to wheel B, receive a compound motion-first, acontinuous rotary motion from shaft D, by which shaft fw is turned onits geometrical axis; second, a variable motion imparted to it fromcrank-handle S, by which shaft 'w is turned upon the geometrical axis ofshaft O, and which operates IOO the threadcarrier in conjunction withthe universal feed. Both these motions are independent one of the other,and can take place at the same time Without any hindrance to one or theother. Thus the thread-carrier b, While revolving around the needle, canbe directed in conjunction With the feed, and will produce a regularseam in al1 directions of the feed.

Pinion 12 is secured to the cylindrical part of frame N, and transmitsits motion to pinion 13, to shaft w, and to pinions Y Z, which latter issecured tothe central tube of the inachine, and thus directs the feed.

Having thus fully described the nature of my invention, I claiml. In anembroidering-machine, the combination, with the continuously-rotatingthreadcarrier, of mechanism, as described, for controlling the movementot' said thread-carrier according to the direction of the feed, as setforth. l v

2. The combination, with the shafts, gearing, and crank-handle forcontrolling the feed, and

the thread-carrier and gearing for transmitting motion to the same, of aframe connected and revolving with one of the shafts operated from saidcrank-handle, a pinion mounted on a crossshaft in said frame andconnected with the train of gearing transmitting motion to saidthreadcarrier, sleeves or cylinders mounted loosely on said shaft andconnected with said pinion and crossshaft by cranks and pitmen, andlevers vibrated by a cam on the main shaft for imparting a reciprocatingmotion to said cylinders,and thereby continuously rotating said pinionand the thread-carrier with which said pinion is connected,substantially as set forth.

In testimony whereof I have signed this specification in the presenceoftWo subscribing witnesses.
